public class LocalConfigKeys
extends CommonConfigurationKeys

This class contains constants for configuration keys used in the local file system, raw local fs and checksum fs. Note that the settings for unimplemented features are ignored. E.g. checksum related settings are just place holders. Even when wrapped with ChecksumFileSystem, these settings are not used.
